Lifedrain

Lifedrain grants your troop the ability to gain health for your champion whenever that troop deals damage. Lifedrain has some of the highest potential of any keyword to swing the course of a game. Giving any stat boost to a troop with Lifedrain goes a long way. If you modify the ATK of the troop, it will be gaining you extra health to keep you alive longer, while if you modify its DEF, than the troop will be more difficult to kill and be able to stay in play longer to gain health over time.

Lifedrain plays particularly well with Steadfast since you will have twice as many chances to gain health in combat, as well as Flight, which allows you to gain health nearly unhindered from the opponent and will force them to find an answer as soon as possible before they find themselves out of the game.

Rules

 * If a card with Lifedrain has no controller, it will cause its owner to gain health.
 * The health gain from Lifedrain occurs at the same time the damage is dealt. It is not a trigger.
 * Multiple instances of Lifedrain are not cumulative.
